Application filed January 9, 1909. Serial No. 471.434.

To all whom it may concern.'

B e it.kiio\vn that I, JOHN C. KENMONTH, a citizen of the United States, residing at Los Angeles, county of Los Angeles, and

les

State of California, have invented new and useful Improvements in Hydrocarbonurners, of which the following is a specification.

My invention relates to a burner for use in stoves and furnaces and the object thereof is to produce a burner' for such uses which vwill buiii the lighter liquid hydrocarbons without the use of an expansible fluid and without producing soot.

Another object is to produce a siinple and and viill not .clog up.

Another object is a; retort is separable froin the other parts and which can 4be easily inspected and cleaned when necessary.

1LFurther objects will be pointed out herea ter.

I accomplish theseobjects b v the -bui'ner j described herein and illustrated in the accompanying drawings. in which;

Figure l is a vlongitudinal -section of the lire box and ash pit of a cool; stove with 111)' improved burner located therein, the saine being partl)v in section. Fig. 2 is a plan of the burner. Fig. 23 is an. enlarged central vertical section of the retort.

in the drawings 5 is a cool; stove of an)v approved ,ronstructionf t3 is the tire box and -the afsh pit of such stove.

Before installing niv iniproved burner the ordinariv grate not shown ,is renioved and in the place of such grate i place `therein `a bed plate S having draft., openings i) therethrough'ncar the ends thereof which extend transversel)Y the plate preferably nearly the Width thereof. These draft openings are wide enough to perinit the inaxiinuni aniount of air for combustion to pass therethrough.

`Between the draft openings the tiring pan l0 which has'in the center thereof a circular opening ll. 'in which is received the retort l2.` A small portion of the bottonil of the pan oriopposite sides of the retort preferably.` slopes upward s shown at 13 in Figs. ylfand 2, so'tha 4 Yhen starting a tire-thev'f'uel when'l ignitedl will burn most freely adjacent the retort. thereby quickly heating the-same) Draft regulating slides or covers 14care provided on each side of the retort and are] longitudinally movable toward or from the retorh therebyY regulatingr the amount of air coining through the draft openings in the bed plate. These covers are preferabl;v concave ou their under side to cause the air passing thereunder to pass close to the surfaceof the fuel in the pan. The edges of these covers adjacent to the retort are preferably nearlyv semi-circular so as to tit closel \Y the retort and thereb'v cut off nearlLvv all the draft through the draft openings in the bed plate when desired.

The bed plate and pan are preferably cast integral and at the ends of the bed plate are transverse grooves l5 so that the plate 1 can be easil)v broken at thefe groovesif the inexpensive burner which is selfA cleaning' provided with cockl may run to a suitable receptacle not shown saine should be too long for the stove to which it is to be fitted. burner in which the rThe retort composed of concentric outer walls 16 and inner walls' 1T unitedbv the top wall 1S and bottoni wall 19. thercbv forming a'n annular vaporizing chamber '10. Un the outer upper side of the outer wall are cas' or otherwise secured thereto stop lugs 21 of which there are pi'eferabl).Y three. but anv other nuniber may be used. or they ina v be.`

dispensed with. I prefer their use as the \Y rest on the top wall of the tiring pan and hold the retort vertical to the` plane of the bed plate and keep ti r retort froin slipping down too far into th'e lash pit.

In the bottoni plate of the vapor. chaniber are openings and 23 the walls of which are screw threaded. In opening 22 screwed the vapor tube 2l, the upper end of whichl is preferably reduced in size and extends to nearly the top of tht,` chamber. A tip 25 having a port 2o in the top thereof is connected to the vaportubc. iciegulating \alve '2T is provided for gontrolling 'the flo-w of vapor froni port 213. in opening 'lis screwed a reducer QS; 'The opening Q9 through this reducer iss-month and is tapered upwardly. In the 'opening 2.5i is received shown. and is provided with a valve Il. tol

regulate and control the flow of fuel therethrough. A branch pipe'il provided with a cock 33 runs from pipe 30. to the tiring pan. Between the connection between pipe 30 and branch pipe 32 and vthe retort there is connected to pipe' 30 a blow ofl"a pipe 3st i This blow off pipe in the cellar or outside the building.

A spreader 36 having legs EET/rests upon the top of the retort and holds the spreader elevated about one and 011e half inches above the retort.l "This spreader is provided to cause the vapor which passes through the central channel 3S of th'e retort when lighted to burn close enough to the top of the retort to heatthe retort.` so as to vaporize the liquid fuel therein. By having the lower portion of the retortl projecting into the ash pit, the retort is kept cool enough to keep the fuel from carbonizing therein and thus prevents-.clogging the retort.

.In the operation of -my burner a supply of liquid fuel would'be first fed into the firing pan and lighted and cock 31 would be partly closed so that the supply of fuel furnished the pan would equal that consumed. Itwill be observed that at the same time fuel will also pass into the retort. As the fuel burns in the pan the fuel in the retort quickly becomes heated and vapor forms in the retort, passes out through port 2G and up to the spreader which dellects it and causes it to become lighted from the flame from the pan. Should there be any sticky residuum on the walls'of the chamber it will boil olf while the retort is being heated. As soon as the vapor begins to burn, cock 33 is closed anud thereafter all fuel is preferably passed through the retort. lYhere an excessively hot fire is wanted, fuel would be supplied at the same time to both the retort and pan.. lVhen there is no longer any use for the fire cocks 31 and 33 would be closed and .cock 35 would be opened. The pressure in the retort would then blow any thick residuum which might be in the retort, out through pipe 34.

By thus construction itwill be observed that the flame from the pan will heat the retort and the stove'as well and that as soon as the retort is hot enough to vaporize .the fuel the further use of the pan may be dispensed with but that it can be used if desired` -It willalso be observedthat any impurities which may collect on the inner walls of the retort when the lire is being 'put out will be boiled olf while the retort is being heated and when the fire is put out these and lany other impurities collected when the re is burning may be blown out through the blow olf pipe. By having a ground connection between the retort and the supply pipe a tight joint is made between lthe parts and a removable retort is provided which can easily be removed from the stove for cleaning or repairs and easily.

put back. By practical experience I have found that by having the vapor pass up in a central channel in the retort 1t entrains air and theeby produces better combustion than if the air was not entrained and enables me to use a heavier grade of fuel without producing soot than can be used when air is not thus entrained. The draftcovers cause the air passing through the draft openings in the bed plate to pass up close to the retort and thereby enter the flame to aid combustion.

4Having described my invention what I claim is.; j l

V1. A. hydrocarbon burner comprising a -bed )late havin@ draft oieninfrs near the ends thereof and a y'central opening therein;

a retort having an amiularchamber therein and a central channel therethrough; a spreader uponI the top of said retort; and

Adraft covers over said dra-ftopenings and longitudinally movable towardor away from said retort whereby the air passing through the openings is caused to pass closer to or farther away from the retort.

A hydrocarbon burner comprising a bed plate having draft openings nearrthe ends thereof, a firing pan having a l,central 'opening therein intermediate said openings.;

a retort having an annular chamber vtherein .and a central opening therethrough in said opening; a spreader upon said retort; means to supply liquid fuel to said pan and retort; means to lead the vapor from the retort and dischargev the saine in the central opening vat the bottom thereof; and draft covers longitudinally movable toward or from said retort whereby the air passing through the draft openings will be caused to approach closely the retort.

3. A hydrocarbon burner comprising a bed plate having draft openings near the ends thereof; a tiring pan intermediate said openings; and draft covers longitudinally movable to project more or less over the firing pan whereby the draft is caused to pass over the pan in close proximity to its surface.

L1. A 'hydrocarbon burner conrprising a bed plate having draft openings near the ends and a retort opening in the center thereof; a retort in said openinglhe lower portion ofwhich projects below the bed plate and the upper portion of which retort projects above the bed plate and draft covers abovefthe draft openings and project-ing toward the retort and longitudinally movable toward and from the retort whereby the air passing through the draft openings is caused to pass more or less closely to the retort.

In witness that- I claim the foregoing I have hereunto subscribed my name this :2nd day of January; 1909.
